What I know is that my daughter's laptop has the above Trojan Horse viruses that have knocked out the AVG control centre, any internet connection and the C drive (probably lots more as well). So I'm doing this on my PC. The HijackThis log file follows - very grateful for your help to recover things:

I've carried out the actions at the preparation guide - less step 5 (Housecall, Panda etc) - this is because the problem is on a laptop where the internet connection has been taken out by the Trojan horse viruses (as well as the AVG control centre). I have, though done a scan with AVG (as well as with Spybot & Adaware).

I also get the following error messages on start-up:

1. Important - potential errors found in system. During a scan of files system start up potential errors in the system registry were found
p-07-100irql:1f SYSVER 0xff00024 NT_Kernel error 12656 KMODE_EXCEPTION_NOT_HANDLED

2.C/WINDOWS/System 32/jkkjh.exe
Windows cannot access the specific device, path or file. You may not have the appropriate permissions to access the item.

I have been unable to complete the RUN: cleanmgr on the laptop as it 'stalls' within seconds of launches and does nothing - there remain a large number of temp internet files (have done a delete files in internet options).
